Using ThreadLocal<RemoteWebDriver>, the FluentWait feature in Selenium allows for seamless synchronization between the test

I am currently seeking a solution to incorporate FluentWaits into my Java Selenium test. The issue I am facing stems from using ThreadLocal to declare my drivers as thread-local in order to run them concurrently.

Below is the code snippet in question:

//Variable declaration
protected ThreadLocal<RemoteWebDriver> threadDriverFirefox = null;

//Setting up driver for each thread in BeforeTest method
threadDriverFirefox = new ThreadLocal<RemoteWebDriver>();
threadDriverFirefox.set(new RemoteWebDriver(new URL(urlnode), DesiredCapabilities.firefox()));

//Method to retrieve the driver
 public WebDriver driverFirefox() {
return threadDriverFirefox.get();
}

//Using the driver in the test
driverFirefox().get(weburl);

The main issue lies with the driverFirefox() method. I am struggling to implement it within the FluentWait structure:

Wait waitfluent = new FluentWait(driverFirefox()).withTimeout(30, TimeUnit.SECONDS)
    .pollingEvery(2, TimeUnit.SECONDS).ignoring(NoSuchElementException.class);

WebElement testElement = waitfluent.until(new Function() {
    public WebElement apply(WebDriver driverFirefox() ) {
    return WebDriver driverFirefox().findElement(By.id("logEmailField"));
    }
});

However, there seems to be a syntax error...

Multiple markers at this line - Syntax error on token ")", delete this token - Syntax error on token(s), misplaced construct(s)

Any suggestions on how to rectify this situation?

Thank you

To prevent memory leaks, it is important to use a static ThreadLocal variable. This ensures that the reference is shared properly without causing any issues. If the ThreadLocal is static, make sure to access it in the correct way. Remember not to initialize the reference by a thread, but only set the value using the set() method.

public class TestEnvironment {

  static ThreadLocal<WebDriver> CURRENT_DRIVER = new ThreadLocal<>();

  public static WebDriver getCurrentDriver(){
    return CURRENT_DRIVER.get();
  }

   public void setupTest(RemoteWebDriver driver) {
    CURRENT_DRIVER.set(driver);
   }
}

You can now easily define a fluent wait using the shared driver:

Wait fluentWait = new FluentWait(TestContext.getCurrentDriver())
                      .withTimeout(30, TimeUnit.SECONDS)
                      .pollingEvery(2, TimeUnit.SECONDS)
                      .ignoring(NoSuchElementException.class);
